Test was done at the Khao Hin Son Research Station, Chachoengsao province during the dry season November 2008-March 2009, the main plots were 4 sweet sorghum varieties (SW1001, SW1002, SW1005 and SW1008) and the sub plots were 4 irrigation frequencies (every 7, 10, 14 and 21 days, four different water amounts 35, 50, 70 and 105 mm, repectively). The results illustrated that sweet sorghum varieties and irrigation frequencies did affect days to flowering, plant height, fresh weight, amount of juice and amount of juice/ton cane. SW1005 gave the greatest amount of juice per 1 ton fresh weight (498 kgs) while SW1008 yielded the lowest (432 kgs). Sweet sorghum grown under the most frequent irrigation (every 7 days) gave the highest juice/ton cane (806 kgs) whereas those under the infrequent irrigation (every 21 days) gave the lowest (275 kgs). The greatest ethanol yield was obtained from SW1001 (79.57 l/rai) and 7 days irrigation frequency (162.82 l/rai).
